STOPPING DEVICE FOR KNITTING-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 534,334, datedFebruary 19, 1895,

Application filed March 31, 1894- Serial No. 505,858. (No model.)

To (ZZZ whom it may concern.-

Be it known that I, CHARLES W. KUTZ, a citizen of the United States,residing at Fleetwood, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in Stopping Devicesfor Knitting-Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to a device for automatically stopping knittingmachines, being intended to operate on the breaking of the yarn.

The invention will first be described in connection with theaccompanying drawings, and particularly pointed out in the claim.

In the drawings-Figure 1 is a side elevation of my stopping devicev Fig.2 is an end View of the same;

Referring to the drawings, A is a supporting bar preferably of wood,rubber or other insulating material, to which is attached a pair ofdownward extending brackets B united at their lower ends by a guideplate I) provided with a bolt hole I) for attachment to machine. To thesupporting bar A is also attached a spring arm 0, having a helicalportion at c and provided with an eyelet c. To hold the spring armagainst lateral motion a slideway D is provided, being attached to theunder side of the bar A. On the supporting bar, A, over the eyelet c isfixed a contact plate Cb. This contact plate extends upward at one endand is provided with a binding post a.

The spring arm 0 is inserted in the supporting bar A at one end as shownin dotted lines in Fig. 1, and is connected to a plate a on the upperside of the said supporting bar, the plate a being provided with abinding post a In using my device the brackets B are attached to thecarriage of the machine by a bolt passed through the bolt hole I), andthe yarn threaded through the eyelet c at the free end of the spring 0,from whence it passes to the yarn guide of the machine as usual.

It will be obvious, to those skilled in the art, that the tension of theyarn will keep the spring arm 0 out of contact with the contact plate a,but in case the yarn breaks the tension will be removed, and theresistance of the spring will cause it to fly upward and touch thecontact plate a.

In order to cause the stoppage of the machine the binding posts a and aare connected by wires to any suitable electro-magnetic beltshiftingdevice, a battery being in the circuit, of course, and energizing theelectro-magnets of the belt-shifter upon the closing of the circuit bythe spring arm 0 touching the plate a, whereby the belt is shifted andthe machine stopped.

I have not described or shown an electro magnetic belt-shifter herein,as any form of such mechanism may be employed in connection with mydevice.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a stopping device for knitting machines and the like, the combinationwith a supporting bar of insulating material, a contact plate attachedto one end thereof and provided with a binding post, a spring armattached to the other end of said bar with its extremity passing throughthe bar and provided with a binding post on the opposite side thereof,the free end of said spring being provided with a yarn guide adapted tocontact normally with said contact plate, a slideway secured to thesupporting bar independently of the contact plate and adapted to guidethe movements of the said spring arm, and brackets arranged on oppositesides of said supporting bar and spring arm and adapted to be secured tothe carriage of the machine, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
